.BALL 0R ROLLER BEARING.

- To all whom it may concern:

vented new and useful Improvements in Ball or Roller Bearings, of which the following is a specification.

This invention relates to ball bearings of the ring type with two or more series of balls and a spherical outer track for one or more of said ball series and has for its ob ject to attain a simple mounting of the bearing without the use of special threadso-r openings for filling in the balls so that the' bearing forms awhole easy tomount and aflording the advantage that the hearing rings are not weakened by recesses or the like, and that there are no parts of the hearing which are liable to loosen and, owing thereto, to damage the bearing or to cause incorrect adjustment of the parts of the bearing in relation to one another.

The invention is also applicable to so called. combined ball bearings, as for instance bearings provided with one ormore serie; of balls adapted to sustain obliquely directed pressures, 0r bearings provided, on the one side, with one or more series of balls 'adapted to sustain substantially radial pressures and, on the other side, with one or more series of balls adapted to sustain substantially axialpressures and so on.-

With these objects in view the invention consists, chiefly, in this that the outer track of one or more series of balls consists of a ring disposed in the outer bearing ring and having a spherical inner sur face, said track ring being adapted to be swung into an oblique position so that the balls can be filled in between said ring and the inner bearing ring whereas the track ring when swung 'to ce'ntral position, closes the opening through which the balls were filled in and at the same time locks the tracks of the other ball series in correct positions.

The invention consists further in detail arrangements and special forms of bearings of the kind mentioned above as will be more explicitly described below.

In order that my invention may be fully understood reference should be made to the accompanying drawings in which Figure 1 shows a ball bearing having two series of balls and a swingable ring located Specification of Letters Patent.

ing a swingable track for the series of balls adapted to sustain obliquely directed pressures. Fig. 7 shows a bearing having three series of balls and Fig. 8 shows a bearing having four series of balls. Figs. '9 and 10 illustrate different forms of combined radial "and axial bearings, and Fig. 11 shows a bearing composed of two ball bearings each of which has two series of balls.

Referring to the drawings, the bearing shown in Figs. 1 and 2 is a ball bearing having two series of balls and provided with outer tracks each .in the shape of a frustum of a sphere whose ends are unequal circles, these tracks may be termed oblique spherical zones, the centers 0: and b of which are located in the planes through the outer edges of the bearing rings. On account thereof, the said bearing is chiefly adapted to sustain radially directed pressures but may also sustain axial pressures 'in the one direction or the other. The inner ring 1 is as usual, provided with tracks for guiding both series of balls 2 and 3. The outer trackof the series of balls 2 is formed by one half of the outer ring 4. while the track of the series of balls 3 is formed by a ring 5 which is inserted in the ring 4: .and

is swingable in relation thereto. When mounting this hearing, one may proceed in the following manner: First the series of balls 2 is placed around the inner ring 1,

"preferably in a ball cage not shown which receives the balls. Then the outer ring of the bearing is pushed in axial direction on the said series of balls, the balls then being 1 Ward in the direction toward the center plane-of the bearing that the balls of the right series of balls may be inserted, one at a time, into the enlarged space or opening between the'outer rim 7' of the ring and the annular rim 8 of the inner ring 1. If desired, the series of balls 3 may also be I I placed in'a ball cage which'is inserted be- 1 may give the ring 5 a successively changed oblique position so that the filling in space according as the balls are inserted, is moved -."a'round the ring. After the balls of thesej -'the axis'of the-ring coincides with the axis 7 A -B of the bearing. The bearing is then I "finished, and the series of balls 3 is retained inf outward direction by the annular rim 8 5:;'and;.if*necessary, also by the ball cage. If

'- desired ia'ball cage common to both series t (of-balls or aseparate ball c g f each lfrisiof balls may be used.

}i" The -swingable track 5 of the series of badlsj;3 -does"not extend to the end surfacev j of thefring 4, and 'a narrow divided retaina I 1n'g. ring 9 may be'insertcd into the" ring Yeoutside of the track 5 preventing uninten- 3 tional swinging of said ring 5. Generally 86.

v s'ary, since the ring. 5 is not exposed to any such alocking device is, however, not neces= swinging forces. Should the retaining ring 9 loosen, the duration of the bearingis not withstanding in no way jeopardized.

. In, Figs. 1 and 2 the track of the series 2 in the outer ring 4 is shown spherical.

. Such a. shape of the track is not, however,- of essential importance for the invention,

since the trackmay be of any suitable shape.

"' 5 The constructional form shown in Fig. 3 differs from that shown in Figs. 1 and 2 chiefly in this that the centers a and b of the spherical tracks are placed outside the outer rims of the tracks. Such a construction ismore advantageous than that shown in Figs. 1 and 2, if the bearing, besides the usual radial load, has to sustain great axial loads or bending. stresses working in an I axial plane. The most suitable magnitude of the angle a between the direction of the ball pressure and the axis A-B of the hearing may be found by a simple calculation purporting to find the smallest value of the ball pressure at given loading conditions.

In the constructional forms shown, in

Figs. 1 to 3 inclusive the outer side as well as the inner side of the ring 5 are of spheri cal shape, and the said ring bears on a surface of the outer ring 4 likewise of spherical shape. The spherical shape of the outer rice 3 have been inserted, the ring 5 is. "swung to central position (Fig. 2) in which sustain oblique pressures.

surface of the ring 4 is not, however, of essential importance for the invention and for the same any other shape may be used.

In the bearing shown in Fig. 4 having two series of balls both series have outer 'out as soon as the rings, after the balls have i been filled in, are swung to central position. I

Fig. 5 shows a combined radial and coni- I cal bearing. The left series of balls 11 serves only to sustain radial pressures and. is. for this purpose placed between a track inthe inner ring-1, and a cylindrical track i' l in the outer ring 4, the latter track being limited at the "inner side by a shoulder, the

cross section of which may be are shaped or the like. The right series of balls, on the contrary, serves to sustain oblique pressures (combined radial and axial pressures) and is located between a track in the inner ring and a swingable ring 5 placed in the outer ring, the inner side of said swingable ring 5 being shaped as a spherical zone having its center 12 outside the end surface of the bearing just as in the constructional forms shown in Figs. 3 and 4. In mounting the bearing, the series of balls '11 is first placed in the inner ring 1, for instance in a suitable ball cage, and then the outer ring 4 is pushed on the said-series of balls. Thereupon the ring 5 is placed in an oblique position in the outer ring 4, and-the balls of the series 3 are'filled in, as described above, whereupon the ring 5 is swung to central position. If 1 10 desired, the ring 5 may be retained in the said position by means of one or more screws- 12, as is shown in the drawing. The bearing shown in Fig. 6 differs from that shown in Fig. 5 mainly in this that in 1 order to retain the ring 5 in central position there is placed outside the bearing ring 4 a sleeve 13 having a flange 14 which covers. the outer end surface of the ring 5. The flanges of the sleeve 13 may be bent after 1 the sleeve has been placed on the ring 4.

Fig. 7 shows a bearing having three series of balls. The left series 15 serves to sustain. axial pressures, the middle series 16 to sustain radial pressures and the right series 3 to t In mounting the bearing the left series of balls'15 is first placed in position, then the balls of the middle series are filled in through any suitable filling opening and finally the right series iaee ae i g;

is mounted in the manner described above by swinging the ring to an oblique position and inserting the balls through the opening formed thereby. When all the balls have been filled in and the ring 5 has been swung to central position, the bearing is' mounted and the three series of balls are'retained in correct positions.

In the bearing according to Fig. 8 having four series of balls all the outer tracks are spherical. The middle series 17. and 18 form a ball bearing having two series of balls, and

- manner as in that bearing. I

Fig. 9 shows a combined axial and radial bearing. The right series of balls 15 serves to sustain axial pressures while the 'left serles 19, serves to sustain radialpressures.

The outer track of the latter series is formed by a swingable ring 5 inserted into the outer ring, the inner surface of said swingable ring' being spherical and having its center a in the plane of the series of balls. In

mounting the bearing, the right series of 30 ring 5 is swung to an oblique position in balls 15 is first put in place .and then the which the balls of the left series 19' may be inserted'in the manner described above. 7

The constructional form shown in Fig. 10

differs from that shown in Fig. 9 chiefly in' this that the left side of the bearing is constructed as a spherical bearing having'two series of balls 20 and 21. -The mounting is effected in substantially the same manner as in the constructional form according to Fig. 9.

i while at the right side the outer track is .each other and by inserting the balls The bearing shown in Fig. 11 is'composed of two spherical bearings each of which has two series of balls. At the left side of the bearing the two series of balls 17 and 18 are placed direct between the inner and outer bearing rings 1 and 4 respectively,

formed by a swingable ring 5. In mounting the bearing both series of balls 17 and 18 at the left side arefirst put in place by swinging the rings of the bearing in relation to through the opening thus formed. Then the balls 20 and 21 at the right side of the hearing are put in place by swinging the ring 5 and inserting the balls through the opening thus formed whereafter the ring 5 is swung to central position.

It will be easily understood that the invention is not limited to the constructional forms shown in the drawing since several other combinations may be used. Further the invention is not'limited to ball-bearings but may also be applied to roller bearings the rollers of which have spherical or other working surfaces. bined' bearings, the parts of the bearings I serving to sustain axial or radial pressures may be constructed with two or more series of balls or rollers.
